The Rules of Play

Which Game to Learn First

  • For two first-timers, 9-Ball. Just hit the balls in order, lowest number first, and you can play right away.
  • For a relaxed game with a larger group, 8-Ball. Split into solids and stripes and take turns.
  • If you’re practicing alone, Bowlliards. Your score shows your progress.
  • Once you’re comfortable, try the point-building game of Rotation, or the call-your-shot games of 10-Ball and 14-1.

Three games use all 15 object balls: 8-Ball, Rotation and 14.1. In every game, the only ball you strike is the white cue ball. The break is taken from behind the head string (the kitchen), with at least one foot on the floor as you strike.

Each game page follows the Nippon Billiard Association (NBA) “Pocket Billiards Competition Rules” (June 2026 revision, in Japanese). Where they differ from the World Standardized Rules (WPA Rules of Play), each page notes the difference.
